  1. Unit 1: MatterStructure and Properties UEQ: How does the structure of matter influence its physical and chemical behavior?

  2. Concept: Physical and Chemical Properties and Changes

  3. Bell Ringer09/05/2012 • Grab your folder!!!! • Have out reflections/notes from yesterday to be stamped! • Look at the display in front of the room… • Describe, in complete sentences, what you see in each box. • Ask the people at your table your 2 questions and see if they can answer them. Work on Test corrections when you are finished!!!

  4. LEQ: What are the differences among solid, liquids, gases, and plasmas? • Pre-read Chapter 16 Section 1 • Write 3 important facts, in complete sentences, about each state of matter that would help you answer the lesson essential question. • Number each fact! • Write 2 Questions that you still have over the reading. • This will count as your reflection tonight!

  5. Vocabulary • Choose 1: How to do Vocabulary: • Write word and definition. Underline and highlight vocabulary word. • Write word on front and definition on back of index cards. • Create a poem or rap of vocabulary words and definitions. • Create foldable with words and definitions. • Create a crossword puzzle. Also make answer key!!! • Kinetic theory • Property • Density • Physical property • Chemical property • Matter • Volume • Physical change • Chemical change

  6. UEQ: How does the structure of matter influence its physical and chemical behavior?LEQ: What are the differences among solid, liquids, gases, and plasmas? • Bell Ringer 09/06/2012 • Write Question and Answer • What is capillary action?

  7. UEQ: How does the structure of matter influence its physical and chemical behavior?LEQ: What are the differences among solid, liquids, gases, and plasmas? • What are the 3 assumptions to kinetic theory? • All matter composed of small particles (atoms, molecules, ions) • Particles are in constant random motion • Particles are colliding with each other and the walls of their containers • Overall, kinetic energy is how fast the molecules are moving and will do so at all temperatures.

  8. UEQ: How does the structure of matter influence its physical and chemical behavior?LEQ: What are the differences among solid, liquids, gases, and plasmas? • Solids • Holds shape! Why? • Definite shape and Definite volume • Not compressible (naturally) because packed tightly • Usually most dense phase of a substance because packed tightly • Exception: water • Definite melting points. Least amount of energy. Movement of particles is slow and around fixed points; but, increases with increase in temperature. • Low rate of diffusion b/c low mobility of particles

  9. UEQ: How does the structure of matter influence its physical and chemical behavior?LEQ: What are the differences among solid, liquids, gases, and plasmas? • Two types of Solids • Crystalline solid • Particles are in an orderly, geometric, repeating pattern • Have definite melting points • Amorphous solid (plastics and glass) • Particles are arranged randomly • No definite melting points

  10. UEQ: How does the structure of matter influence its physical and chemical behavior?LEQ: What are the differences among solid, liquids, gases, and plasmas? • Liquids • Definite volume but no definite shape • Take shape of container • Particles free to move/slide past one another; but, still held together by intermolecular forces • Cannot be compressed under common pressure • Can transmit pressure equally in all directions • Usually less dense than solids; but, more dense than gases • Diffuses at average speed

  11. UEQ: How does the structure of matter influence its physical and chemical behavior?LEQ: What are the differences among solid, liquids, gases, and plasmas? • Surface Tension • Drawing molecules together to decrease surface area • Predict: How many drops of water do you think will fit on a penny? Was your prediction correct? • Capillary Action • When surface of a liquid and solid meet, surface of liquid molecules are pulled upward, against the pull of gravity, along surface of solid • Meniscus • Observation: What is reading on the graduated cylinder?

  12. UEQ: How does the structure of matter influence its physical and chemical behavior?LEQ: What are the differences among solid, liquids, gases, and plasmas? • Gases • No fixed shape, no fixed volume • Too much energy to remain attached. Particles vibrate at high speeds. • Gas takes shape of container by expanding • Less dense than solids and liquids • Still considered a fluid • Can be compressed easily with very little pressure. However, once it is contained, it want to escape the container.

  13. UEQ: How does the structure of matter influence its physical and chemical behavior?LEQ: What are the differences among solid, liquids, gases, and plasmas? • Diffusion • Spontaneous mixing of particles of two substances caused by random motion

  14. UEQ: How does the structure of matter influence its physical and chemical behavior?LEQ: What are the differences among solid, liquids, gases, and plasmas? • Plasmas • Once molecule is superheated, electrons leave the atoms in the molecules • +/- charged particles • Stars, lightening bolts, neon/fluorescent bulbs, auroras

  15. UEQ: How does the structure of matter influence its physical and chemical behavior?LEQ: What are the differences among solid, liquids, gases, and plasmas? • Exit slip • State of matter with indefinite volume and indefinite shape • State of mater with definite volume and definite shape • State of matter with definite volume and indefinite shape

  16. UEQ: How does the structure of matter influence its physical and chemical behavior?LEQ: What are the differences among solid, liquids, gases, and plasmas? • Bell Ringer 09/07/2012 • Describe and illustrate the physical differences among solids, liquids, and gases in terms of their mass, volume, density, shape, and particle arrangement.

  17. UEQ: How does the structure of matter influence its physical and chemical behavior?LEQ: What are the differences among solid, liquids, gases, and plasmas? • Homework: • Continue to work on Vocabulary. Due Tuesday! • Write Questions and Answers • Pg. 483 #’s 1, 2 • Pg. 500-501 #’s 5, 8, 12, 16 • Pg. 502 #s 1, 4, 6, 19
